What does "work out" mean in this sense?
Examples
- We still need to work out the details of the contract before we can sign anything.
- Have you worked out how much it's all going to cost?
- The schedule hasn't been worked out yet, but we'll have it ready by Friday.
How to use it
The most common pattern — use a specific noun as the object, such as 'the details', 'a plan', or 'the cost'.
We need to work out the schedule before we send any invitations.
With short noun phrases, you can also place the object between 'work' and 'out' — both orders are correct.

When the object is a pronoun like 'it' or 'them', it must go between 'work' and 'out' — you cannot put it after 'out'.
The budget looks complicated, but I'm sure we can work it out.
Very commonly followed by a question word like 'how', 'what', 'where', or 'when' to introduce a clause describing what needs to be planned.
We haven't worked out how to get everyone to the venue yet.
The passive form is natural, especially in formal or written contexts, when describing something that still needs to be planned or has already been decided.

Common Mistakes
When the object is a pronoun like 'it' or 'them', it must go between 'work' and 'out'. Putting it after 'out' is ungrammatical in English.
'Figure out' focuses on understanding or solving a puzzle, while 'work out' in this sense is about planning or calculating the specifics of something. They overlap, but 'work out a plan' or 'work out the budget' sounds more natural than using 'figure out' in the same way.
It sounds awkward to put a very long noun phrase between 'work' and 'out'. With long phrases, keep the object after 'out'.
Usage
This phrasal verb is neutral in register and works in both spoken and written English, from casual conversations to business meetings. It is very commonly followed by a question word: 'We need to work out how to do this.'
do exercise to get fit or stronger
Sense 2: What does "work out" mean?
Examples
- She works out at the gym three times a week to stay healthy.
- He's been working out every morning since January and he looks much fitter.
- Did you work out yesterday, or did you take a rest day?
How to use it
This is the basic pattern — 'work out' is used without any object because it describes the action of exercising.
She works out every morning before going to work.
Frequency expressions like 'every day' or 'three times a week' are very commonly used with this phrasal verb.
He tries to work out at least four times a week to stay fit.
You can add a location phrase to say where the exercising happens.
They prefer to work out at home rather than at the gym.
A 'to + verb' clause is often added to explain why someone is exercising.
She started working out to build muscle and improve her energy levels.
Common Collocations
Common Mistakes
In this exercise sense, 'work out' never takes an object — you cannot put a noun or pronoun between 'work' and 'out' or after 'out'. If you add an object, you change the meaning to 'solve' or 'calculate'.
The phrase 'work out' can also mean to solve or calculate something, and that sense always has an object after it. If you see or use 'work out' without any object, it means exercise — not solve.
'Work up' in a fitness context means to gradually produce something like a sweat or an appetite, and it always needs an object. It is not a general word for exercising — use 'work out' for that.
Usage
This phrasal verb is neutral and widely used in both British and American English. The related noun 'a workout' is very common — native speakers often say 'I had a great workout' rather than using the verb form.
calculate an amount, cost, or answer
Sense 3: What does "work sth out" mean?
Examples
- Can you work out how much we each owe for the meal?
- I worked the total out on my phone — it comes to about £85.
- The exact cost hasn't been worked out yet.
How to use it
The most common pattern — use it when the object is a short noun phrase referring to a number, cost, or result.
Let me work out the total before we ask for the bill.
The object can be placed between 'work' and 'out' when it is a short noun phrase — both word orders are natural.
She worked the discount out on her phone and told us the final price.
When the object is a pronoun, it must go between 'work' and 'out' — you cannot say 'work out it'.
The prices looked complicated, but he worked them out pretty quickly.
Use this pattern when the calculation is expressed as an embedded question — the clause comes after 'out', not before it.
Can you work out how many tiles we need for the bathroom floor?
The passive form is natural when the focus is on the result of the calculation rather than who did it.
The delivery charges have already been worked out and added to your order.
Common Collocations
Common Mistakes
In this sense, 'work out' always needs a number, amount, or measurable result as its object. If your object is something abstract like a plan or a decision, you're using a different sense of 'work out'.
When the object is a pronoun like 'it' or 'them', it must come between 'work' and 'out'. Placing it after 'out' is incorrect.
When your object is a clause starting with 'how much', 'how many', or 'what', keep 'work' and 'out' together and put the clause after 'out'. Do not try to split 'work' and 'out' around a long clause.
Usage
This sense is neutral and very common in everyday British and American English as a less formal alternative to 'calculate'. It frequently appears with embedded question clauses: 'work out how much / how many / what the total is'.
happen or develop in a certain way (well or badly)
Sense 4: What does "work out" mean?
Examples
- I was really worried about the move, but everything worked out fine.
- Do you think the new business plan will work out?
- Unfortunately, the relationship didn't work out, and they split up last year.
How to use it
The subject is almost always a pronoun like 'it', 'things', or 'everything', or an abstract noun referring to a plan or situation.
Everything worked out in the end, so there was nothing to worry about.
An adverb showing the result or direction of development usually follows — without it, the meaning can be unclear.

Time adverbials like 'in the end' or 'eventually' are often added to show that a positive result came after a delay.
It was a stressful few months, but the job situation worked out eventually.
The negative form is commonly used to describe plans or relationships that failed, often without blaming anyone directly.
Their business partnership didn't work out, so they decided to go their separate ways.
Future forms are very common in reassuring someone or expressing hope about an uncertain situation.
I know things feel difficult right now, but I'm sure it's going to work out fine.
Common Collocations
Common Mistakes
In another sense, 'work out' means to calculate or solve something and takes a direct object ('work out the cost'). In this sense, there is no object — the subject is a situation, not a person doing a calculation.
Saying 'it worked out' on its own can sound incomplete. Adding an adverb like 'well', 'fine', or 'badly' makes the meaning clear and sounds more natural.
In this sense, the subject should be a situation, plan, or abstract thing — not a person actively doing something. A person as subject usually signals the exercise sense ('she works out every morning') or the calculating sense.
Usage
This phrasal verb is neutral and works in both spoken and written English. It is especially common in reassuring someone ('I'm sure it'll work out') or reflecting on how a situation ended ('it worked out well in the end').
have a good or successful result

Common Collocations

Usage
This is a neutral, everyday expression used in both British and American English. It is especially common in spoken English when talking about relationships or plans that succeeded or failed.
Frequently Asked Questions
Does 'work out' always mean to plan something? I've heard it used in other ways.
No — 'work out' has several different meanings in English. It can also mean to exercise physically ('I work out every morning') or to describe something going well or ending in a certain way ('I hope it all works out for you'). The planning sense always has a specific object or a question word like 'how' or 'what' after it, which helps you identify this meaning.
What kinds of things can you 'work out'?
You typically 'work out' concrete things that require thought or calculation, such as details, plans, costs, schedules, budgets, deals, solutions, and routes. You can also 'work out' how to do something, what to do next, or when something will happen. The object is almost always something specific and practical.
Can I use 'work out' in formal writing, like a business email?
Yes, 'work out' is neutral in register and is perfectly appropriate in professional and business contexts. You might see it in emails, reports, and meetings ('the logistics still need to be worked out'). If you want a more formal alternative, you could use words like 'devise', 'formulate', or 'determine', but 'work out' is not considered informal or inappropriate.
Can I say 'work out' without an object, like 'Let's work out before the deadline'?
In the planning sense, no — you always need a specific object or a question word clause after it. Without one, the sentence belongs to a different sense of 'work out', such as exercising or something going successfully. Always include what you are planning: 'Let's work out the details before the deadline.'
Does 'work out' always mean exercise?
No — 'work out' has more than one meaning. It can also mean to solve or calculate something (e.g. 'work out the answer') or to develop in a particular way (e.g. 'things will work out fine'). The exercise sense is easy to spot because no object follows the phrasal verb, and it is often used with location or frequency phrases like 'at the gym' or 'every day'.
Is 'workout' one word or two? How is it different from 'work out'?
'Workout' (one word) is a noun — it refers to a single session of exercise. 'Work out' (two words) is the phrasal verb. You might say 'I had a great workout today' (noun) or 'I work out every morning' (verb). Both forms are very common and natural.
Can I use 'work out' to describe one specific moment of exercising, or is it only for habits?
You can use it for both. It is very common for habits ('She works out three times a week'), but you can also use it for a specific past action ('Did you work out yesterday?') or a plan ('I'm going to work out this evening'). All of these are natural.
What kinds of adverbs or phrases go well with 'work out'?
The most natural companions are frequency expressions like 'every day', 'regularly', or 'five times a week', location phrases like 'at the gym', 'at home', or 'in the park', and manner adverbs like 'hard'. You can also add a purpose clause like 'to stay fit' or 'to build muscle'.
Does 'work out' always mean calculate? It seems to have other meanings too.
You're right — 'work out' has several different meanings in English. This particular sense specifically means to calculate or find a numerical answer. Other meanings (like exercising or planning something) are handled separately on this platform. The key sign that you're in the calculate sense is that the object is always a number, amount, or measurable quantity.
Can I use 'work out' in the present continuous, like 'I am working out the total'?
It's not wrong, but it sounds unusual in this sense. In everyday English, people almost always use the simple tenses instead: 'I'm working out the cost' is possible but rare, whereas 'I worked out the cost' or 'I'll work out the cost' feel much more natural.
Is 'work out' different from 'figure out' when talking about calculations?
'Work out' and 'figure out' overlap a lot in this meaning and are often interchangeable. The main difference is that 'figure out' can sound slightly more informal and sometimes suggests more effort or puzzlement. 'Work out' feels a little more neutral and straightforwardly mathematical.
Can 'work out' be used in the passive?
No — in this sense, 'work out' is intransitive, meaning it has no object. Because there is no object, a passive form is not possible. You can only say 'it worked out well', not 'it was worked out well'.
Does 'work out' always mean something positive?
Not always. It describes how something develops, which can be positive or negative. 'It worked out well' is positive, but 'it didn't work out' or 'it worked out badly' describe a negative result. The phrase is actually quite neutral on its own.
What kinds of things can be the subject of 'work out' in this sense?
The subject is almost always an abstract noun or pronoun — things like a plan, a relationship, an arrangement, a situation, or simply 'it', 'things', or 'everything'. You wouldn't normally use a person as the subject in this sense.
What's the difference between 'work out' and 'turn out'?
'Turn out' focuses on the final result or what was discovered ('it turned out to be easier than expected'). 'Work out' puts more emphasis on a process coming to a resolution, and it very often collocates with 'well', 'fine', or 'in the end'. In many sentences they are interchangeable, but 'work out' is more common in reassuring contexts.
Can I use 'work out' in the present continuous — like 'it is working out well'?
It's grammatically possible, but it sounds a little unusual in this sense. Native speakers more often use the past simple ('it worked out well') or future ('it'll work out'). If you want to talk about an ongoing positive development, 'it seems to be going well' is often more natural.
Can 'work out' have other meanings? I've heard it used differently.
Yes, 'work out' has several other meanings in English — for example, doing physical exercise or calculating something. However, this entry focuses only on the meaning of 'prove successful', which is always intransitive and never takes an object.
Can a person be the subject of 'work out' in this sense?
No — in this sense, the subject is always a thing, a situation, or a vague word like 'it', 'things', or 'everything'. If a person is the subject in a similar structure, it usually signals a different sense of 'work out'.
Is 'everything will work out' natural to say to someone who is worried?
Yes, it's very natural and commonly used to reassure someone. Phrases like 'everything will work out' or 'it'll work out in the end' have a warm, optimistic tone and are frequently heard in everyday spoken English.
Is 'work out' used in both British and American English?
Yes, this sense of 'work out' is used in both varieties of English with no significant difference in meaning. It's a neutral, everyday expression suitable for both spoken and written contexts.
